Answer:
Explanation:
NADH and FADH2 are both electron carriers of the electron transport chain. NADH gives up its electrons starting from Complex I, which has a higher energy level compared to other complexes. Energy is given off to pump protons across the membrane by the time electrons are transferred to ComplexIII. More electrons are pumped across the membrane as electrons move to Complex IV. Because NADH commenced giving up its electrons from Complex I (higher energy level complex), more protons are pumped across the membrane gradient, which enables ATP synthase with more power to produce 3ATP molecules per NADH molecule.
On the other hand, 2 molecules of ATP are generated by FADH2 because it starts by giving up its electrons to ComplexII. It missed a chance to pump protons across the membrane when it passed Complex I. By the time the electrons reach Complex IV, less protons have been pumped. The lesser the protons to power ATP synthase, the lesser the ATP molecules produced.
The right answer is A.Transcription uses uracil.
The genes carried by the DNA will be encoded in another form: messenger RNA, during a process called "transcription".
The DNA and RNA molecules are chemically very close, but the second has an extra oxygen (in red on the right of the letters) on the sugars (riboses) that make up its nucleotides (the DNA actually contains deoxyribose). In addition, the thymine (T) of DNA is replaced by uracil (U) in RNA.

Answer:
As the diagram for the question is not given, lets answer the question generally.
Explanation:
Energy in a system is neither created nor destroyed. Yet, the energy can be changed from one form to another. If in the beginning, at a point a, an object has a potential energy of 100 joules, then at point b the kinetic energy of the object will be subtracted from the total 100 joules of energy present in the beginning. This is because the potential energy will be being changed to the kinetic energy and no new energy will be created or destroyed.
<em>both producers and consumers are the part of ecosystem but finally either directly or indirectly they become food of the decomposers that may be micro-organisms or the larger parasite or saprophyte ..
